Re: C2500 DRAM problem [7:24954]
Good information - Thanks Johan. Managed to get the tests to run and all passed fine. Doesn't explain why I can't get the 12.2 image on. I'm going to mess around with another TFTP server, although I've never had any problems with Pumpkin before. Otherwise I'm running out of ideas, unless anybody does know how to turn off the checksum feature I'll try an older image just to make sure everything goes back on.

RE: C2500 DRAM problem [7:24954]
I had the exact same trouble with the bootstrap memory test, so I searched the CCO and came up with the following links: Bootstrap Program http://www.cisco.com/univercd/cc/td/doc/product/access/acs_fix/cis2500 /2505/2500him/76996.htm (Watch the URL-wrap!) Bootstrap Diagnostic Tests http://www.cisco.com/univercd/cc/td/doc/product/access/acs_fix/cisigslr/igslrhir/22757.htm (Watch the URL-wrap!) Seems like you have to set the config-register to 0x0 before useing the memory test!? /Johan Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=25185&t=24954 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Re: C2500 DRAM problem [7:24954]
I've pasted in the results of a memory test on a 2500 below. Anybody know if this is normal? Seems to give me a fair few options, then do very little before it reboots (I've snipped it at the point it starts to reboot). I've been messing around with a 12.2 image and constantly get invalid checksum after tftp. I've had this before on the same router with 12.1. I just kept trying it last time and eventually it went in OK. I dare say it will do the same this time eventually. Once it's in there are never any problems. Gaz >T ?

Re: C2500 DRAM problem [7:24954]
the problems with DRAM occur because: 1. You try to install PC SIMM memory that is NON-parity memory. The routers require PARITY memory. 2. You have memory that is not fast enough (70 ns maximum) I've never had a problem with flash memory installations, so I can't comment on that. Not all memory is created equally ;-) -e- - Original Message - From: "Matthew Crane" To: Sent: Friday, November 02, 2001 4:20 AM Subject: RE: C2500 DRAM problem [7:24954] > Hi Johan > > There is generally nothing special about DRAM or Flash they are certainly > usable in other systems so they are not of a proprietary design. > > We have had problems with some 3rd party DRAM and Flash in the past usually > due to poor handling at the manufacturer.

RE: C2500 DRAM problem [7:24954]
Hi Johan There is generally nothing special about DRAM or Flash they are certainly usable in other systems so they are not of a proprietary design. We have had problems with some 3rd party DRAM and Flash in the past usually due to poor handling at the manufacturer. Try taking the DRAM out putting it on an anti static bag or rubber mat and then rub very gently over the pins with a pencil eraser. Do both sides of the pins then re-insert the DRAM and try again.

RE: C2500 DRAM problem [7:24954]
Not being an expert in memory testing, but I know that you can control-break the router during startup and do a T M (test memory). Try and see...

C2500 DRAM problem [7:24954]
I've got some problem with a couple of 16MB DRAM modules for my C2500 routers. I bought non Cisco memories for my lab routers, but I get Parity Error alot and the router just reboots. I also bought non Cisco flash modules, but these seems to work just fine. Is there some way to run a verbose check on the memory so that I can sort out if the problem is the router or the memory?
